Your Israeli passport should allow visa-free entry into Russia. The war in Ukraine strained relations between the two countries but not to the level of denying entry.
Israel currently has not travel warnings regarding Russia (Hebrew source), except for specific ones for Chechnia and crossing into Georgia. Regarding covid-19, the same site says travel is "allowed but not recommended" - same as most world countries.
A significant challenge may be getting money while in Russia. I believe most non-Russian credit card will not work, so check your options with care.
